Question

(forces and motion) explain in 3-2 sentences why acceleration is interesting.

Answer 1

Acceleration denotes to rate of change of velocity

Or

• a=dv/dt

Acceleration can. be both negative and positive .

Acceleration Is important because of Newtons second law which states that F=ma m

Answer 2

• Acceleration is a vector and is the rate at which an object changes its velocity. Acceleration is not going fast.
• If a person is moving fast but not changing speed, he is not accelerating.
• The person or object has to be going fast sometimes, faster sometimes, or slower sometimes.
